`Referring `to the drawings the invention is shown as comprising a barrel A which lterminates at one end in a receiver B from which latter depends the handle C. The receiver B is provided with a breech chamber 20 opening through the upper side of said receiver and communicating with lthe ybore ofthe barrel A and also with a magazine receiving passage 21 formed in the .handle C. Slidably mounted inthe chamber Aend the breech block is provided with side and bottom walls, the left hand side wall of said block being provided with a slot 23 for a .purpose that will hereinafter appear. The bottom wall of the breech block E is provided with a longitudinal groove 24e which opens through lthe forward end of said breech block. The top-of the breech block is provided with a longitudinal recess 25 which extends partly into the closed front end of the breech block. `Mounted within :the breech block E between the rear end thereof and the partition 22 is a rod 26 encircled by a recoil spring 27 one end of which `bears against the partition 22, while the other end thereof bears against a projection 2S `formed on a block 29 fiXedly secured 4'to the receiver B, said .projection 28 being provided withlan opening -30 through which the rod v26 is .adaptedto slide. By this construction it will be apparent lthat the spring 27 will const-antly tend to move the breech block E to closed position and that the retraction of g f v. j Y A-1,078,224-

an opening 34 in the front end of the breech block and engage the primer of a cartridge disposed in the ammunition chamber of the barrel A. The firing pin stem 32 is enlarged laterally betweenthe partition 22 and the front end of the breech block and this enlarged portion of said stem extends through the slot 23 and is provided with a'shoulder v35 for a purpose that will hereinafter appear. Pivotally mounted in the recess 25 is an .extractor arm 36 the forward end of which is provided with a nib 37 adapted to engage over the rim of a cartridge when the breech block is closed so that when the breech block is retracted the extractor arm will effect the withdrawal of the empty shells from the ammunition chamber of the barrel. Seated in the recess 25 is a spring` 38 which constantly bears against the inner end of the extractor arm 36 and serves to maintain the nib 37 in operative engagement with the rim of a cartridge. The nib 37 is provided with a beveled face which rides over the rim of cartridge during the closing of the breech block and allows the nib to pass into engagement with the cartridge rim. Encircling the firing pin stem 32 and having one end bearing against the enlarged portion of said stem and its other end bearing against the partition 22 is a firing pin spring 39.

YSecured to the handle C and the receivei yB is a trigger guard 40 within which is slidnected an ear 43 formed on a sear tripping plate 44, said plate 44 being provided on its upper side with a sear engaging shoulder 45. Formed on the plate 44 and projecting from the end thereof remote from the ear 43 is a finger 46 adapted for engagement with a curved face 47 formed on the breech block E during the movement o-f the breech block so as to hold the plate 44 out of sear engaging position against the infiuence of a spring 47 interposed between the trigger 41 and the plate 44 near the pivoted end of the latter. lit will be here noted that the receiver B is recessed on its left hand side just above the trigger 41 to receive the plate 44 and other mechanism to be hereinafter referred to and it will also be noted that this recess is sufficiently deep to afford communication between the same and the recess Y in which the breech block E slides so as to permit certain parts of the mechanism to operate in said lateral recess and also in the recess wherein the breech block reciprocates.

YPivotally mounted in the lateral recess ofthe receiver B above the plate 44 is a sear 48 in the form of an angle lever and having o-ne arm thereof provided with a shoulder 49 adapted for coperation with the shoulder 45, while the free end of the other arm of saidV sear projects in the recess 20 and is adapted to coperate with the shoulder 35 on the iiring pin stem to eect the cocking of the firing pin upon the return of the breech block E to closed position under the influence of the recoil spring 27. The sear 48'is normally held in position to coperate with the shoulder 35 by means of a spring `5O interposed-between a fixed partY of the with a recess 51 between the side walls of which is mounted a rod 52 and upon this rod is slidably mounted a block 53 provided with a locking lip 54 on the end thereof adjacent the free end of the plate 44. The block 53 is normally held at the limit of its movement toward the free end of the plate 44 by a spring 55 which encircles the rod 52 and has one end in engagement with the side wall of the recess 51 and its other end in engagement with the block 53.

Formed on the receiver B and projecting into the lateral recess of said receiver is a lip 56 beneath which the lip 54 of the block 53 is adapted to engage underV predetermined conditions to hold the plate 44 against movement to sear engaging position under the iniiuence of the spring 47. rl`he mechanism just described is confined within the lateral recess of the receiver-by a cover plate 57` K which may be readily removed when desired so as to aiiord access to the mechanism contained in the lateral recess of the receiver.

Formed in the left hand side of the receiver B is a longitudinal groove 58 one end of which communicates with the lateral recess of said receiver. Mounted for movement in the groove 58 is a safety slide 59 which is provided on the inner face of its forward end with a lug 60 having a beveled edge 61 adapted for coperation with a beveled edge 62 formed on the free end of the plate 44. The rear end of the slide is provided with an inwardly projecting pin 63 which is adapted to spring into a recess 64 formed in the bottom of the groove 58 whereby said slide is locked against accidental movement from inactive to active position. The slide 59 is further provided at its rear end with a thumb piece 64 whereby the same may be conveniently operated ment with the Vpin 7 0 when it will be thrown 21 of the handle C is a magazine casing 65 in which is disposed the usual feed spring `66 and followerplate 67, the action of said ment from the Vpassage 2l by means of a spring controlled latchv68 which is adapted to engageV over a projection 69 formed on said casing 65.

Mounted in the receiver B in the bottom` of the recess 20 is a pin 70 which projects Vinto-the groove 24 o-f the breech block and overlies the rear side of the passage 21, said ed cartridges in the magazine and of also eifecting the ejection of the empty cartridge shell upwardly through the recess 20 during the final retractive movement of the breech block after firing.` The rear end of the receiver B is provided with a recess 71 in which is pivotally mounted a latch 72 provided with a lip 7 3. Mounted in the recess 71 is a spring 74 which serves to lock the latch 7 2 in either active or inactive position. In the active position of the latch 72 the lip 7 3 is adapted to engage in a recess 7 5 formed in the rear .end of the breech block E vand whereby said block is locked against accidental retraction.

Assuming the parts to be in the position shown in Figs. 2 and 17 the operation of the iirearm upon firing will be as follows. By

pulling the trigger 41 rearwardly against the influence of the spring 42 the plate 44 will likewise be drawn rearwardly and this movement of the plate 44 will cause the shoulder 45 `to engage the shoulder 49 of the sear 48 and rock said sear so as to'disengage the same from the shoulder 35 of the firing pin thereby releasing the firing pin to t-he influence of the spring 39. The

firing pin will then be moved forward and fire the cartridge disposed in the ammunition chamber of the barrel A. The recoil resulting from the firing of the cartridge will react upon the breech block E and retract the latter against the'influence of the recoil spring 27. During the retraction of the breech block E the extractor arm 37 will draw the empty cartridge shell rearwardly until said shell comes sharply into engageupwardly out of the recess 20. During this retraction of the breech block the linger 46 will engage the curved face 47 of the breech block and as a result thereof said nger and the plate. 44 will be forced downwardly so as to withdraw the shoulder 45 from engagement with the shoulder49 of the sear copies of this pafeiitfmay be ohtaineafor the shoulderV 35 as the breech block is returned to closed position by the spring 27. This return movement of the breech block under the influence of the spring 27 will force the uppermost cartridge in the magazine into the Vammunition chamber of the barrel and as previouslyI stated will bring Athe shoulder 35 into engagement with. the

sear 48 and thus automatically cock the firing pin. This operation is repeated each time Vthe firearm is discharged. As the trigger 41 is drawn rearwardly against the influence of the spring 42 the lip 54 of the block 53 will ride over the beveled forward end of the projection 56 and upon the retraction of the breech block the downward movement of the plate 44 as a result of the coperation of the finger 46 with the curved face 47 will cause the block 53 to move inwardly of the plate 44 against the influence of the spring 55. As soon as the lip 54'of the block 53 has passed beneath the projection 56 the` spring 55 will operate to engage the lip 54 beneath said projection 56 and in this manner the plate 44 willbe locked against upward movement into operative relation with the sear 48 until ressure on the trigger 41 is entirely removed.

In order to lock the mechanism against .tiring it is only necessary to operate the slide 59 forwardly of the firearm when the beveled edge 61 of the lug 60 will engage the beveled edge 62 of the plate 44 and thus force said plate 44 downwardly out of operative relation with respect to the sear 48. With the plate 44 held in this position by the operation of safety slide it will be apparent that the rearward movement of the trigger 41 and the plate 44 will not disengage the sear 48 from the shoulder 35.

What I claim is In an automatic iirearm, the combination of a receiver, a breech block slidable in the receiver, Vsaid block having a hollow interior opening through its side walls and bottom, a partition dividing the interior of the block into front and rear chambers, a longitudinal rod in the rear chamber having in its forward Vend an opening coinciding with an opening 'through the partition, a firing pin slidable in said openings, spring means constantly tending to move said pin to firing position, a lateral projection on said pin eX- tending through the side wall of the block, and a scar on the receiver for engaging said projection during counter recoil to move the firing pin to retracted position.

In testimony whereof, I afIiX my signature in the presence of two witnesses.
